IMPROVED APPARATUS FOR CARBURETING GAS.

Specification forming part of Letters Patent No. 64,776,'dated May 14, 1867.

To all whom it may ,conoern:

Be it known that I, W. H. LAUBACH, of Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a new and Improved Method of Regulating the Flow of Gas and Improving its Quality; and I do here by declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

This invention-relates to a method by which the common street-gas is improved or enriched by passing over it hydrocarbon liquid,

and to the manner in which the flow 'of the gas is regulated; and the invention consists in providing suitable vessels and chambers, pipes and cooks, whereby I am enabled to greatly improve the quality of the gas, and to regulate the flow thereof by a float and valve, in the manner hereinafter more fully described.

Figure 1 representsa reservoir of volatile hydrocarbon liquid. Fig. 2 represents a vessel containing hydrocarbon liquid. over which the gas passes to the regulator. Fig. 3 is a horizontal section of the same on the line a: m. Fig. 4 is the regulator, showing the regulatingvalve, the cistern and float, and the gas-passages. Fig. 5 is a horizontal section of the same through the line y 3 Similar letters of reference indicate like parts.

A is the regulator. A represents a vessel, which contains volatile hydrocarbon liquid; it is a reservoir, from which a suitable quantity is discharged into the vessel below, marked B. The gas enters this vessel through the pipe 0, and, following the spiral passage-Way formed by the scroll in the interior of the vessel, marked 0, in contact with the liquid, it becomes loaded or saturated therewith, and is through which the gas passes.

-or falls with the float.

discharged from thence with the regulator through the pipe D. E represents a central pipe, with an aperture through its upper end, The size or area of this aperture isregulated by a valve, F, which is conical in shape, and which is attached to a float, G, and moves up and down I with it. This float may be suspended from above, and adjusted for a certain pressure,

forming a chamber within, into which the gasis discharged from the pipe E. The cistern or annular space around the pipe E (marked H) is filled with Water to about as far as is indicated in the drawing by the line 70. When the pressure of the gas increases or diminishes the float G will rise or fall, and consequently the aperture through the pipe E will be enlarged or diminished as the conical valve rises The gas is discharged from the regulator through the pipe J into the service-pipe.

2. I claim the combination of regulator A and the hydrocarbon-vessel B, substantially as described.
